ESP-01 Programmer Adapter

The ESP-01 Programmer / Adapter provides a convenient USB interface for programming, debugging, and communicating with ESP-01 modules. It integrates a CH340C USB-to-UART converter, NodeMCU-style automatic reset and flash circuitry. A dedicated 6-pin male header provides direct access to GND, 3.3 V, RX, TX, IO0, and IO2, allowing IO0 and IO2 to be conveniently used as external GPIOs. Features: ESP-01 Interface: 8-pin female header for direct connection to ESP-01 modules. USB Interface: USB Type-B connector with integrated CH340C USB-to-UART converter. 3.3 V Power Supply: Buck-regulated 3.3 V output, up to 600 mA. UART Access: Direct RX and TX connections through the external header. GPIO Access: IO0 and IO2 exposed through the external header for convenient GPIO use. Programming: Automatic: NodeMCU-style auto-reset and auto-flash circuitry. Manual: Dedicated RESET and FLASH buttons. Status Indicators: Green: PWR LED. Yellow: TX/RX activity LEDs. Grounding: Chassis ground isolated from circuit ground. PCB Dimensions: 43.4 mm × 26.8 mm.
